Effects of Soil Pollution
1. : Considering how soil is the reason we are
able to sustain ourselves, the contamination of it has major consequences on our
health. Crops and plants grown on polluted soil absorb much of the pollution and
then pass these on to us. This could explain the sudden surge in small and terminal
illnesses.
2. : The ecological balance of any system gets
affected due to the widespread contamination of the soil. Most plants are unable to
adapt when the chemistry of the soil changes so radically in a short period of time.
Fungi and bacteria found in the soil that bind it together begin to decline, which
creates an additional problem of soil erosion.
3. : The toxic chemicals present in the soil can
decrease soil fertility and therefore decrease in the soil yield. The contaminated soil
is then used to produce fruits and vegetables which lacks quality nutrients and may
contain some poisonous substance to cause serious health problems in people
consuming them.
4. : The emission of toxic and foul gases from
landfills pollutes the environment and causes serious effects on health of some
people. The unpleasant smell causes inconvenience to other people.
5. : The death of many soil organisms (e.g.
earthworms) in the soil can lead to alteration in soil structure. Apart from that, it
could also force other predators to move to other places in search of food.
X. Read the passage carefully and do the tasks.
There are many kinds of pollution. Air, water, and land can be polluted. Some pollution is caused by
nature, such as foods, forest fires, and volcanoes. People are the major Cause of pollution. We pollute the
air with our cars, homes, and factories. Smoke from factories and car exhaust makes the air looks gray and
smoggy. Some people cannot go outside when the air is very bad! We pollute the water by dumping
garbage and Chemicals in the water. Plants and animals die because of the pollution in the water. We
pollute the soil with Chemicals and garbage. We harm the land by cutting down trees in the forest,
especially to build roads and new houses without careful planning and thinking.
The only way to save our environment is to think about pollution. How can you stop or limit pollution?
How do we protect our environment? Conservation is one way to protect our environment. Conservation is
the wise use and protection of our environment. We can control water pollution by not producing as much
as waste and by proper disposal of sewage and garbage. We can take care of recreation land by cleaning up,
after ourselves and not causing more pollution. Carpooling and public transportation will help reduce air
pollution.

V. Choose the letter A, B, C or D to answer these following questions.
There are many causes that lead to water pollution. One main cause of this issue is wastewater coming from many factories and then being directly pulled out into water bodies, especially into rivers or seas without any treatment because this is the most convenient way of disposing wastewater. Industrial waste consists of some kinds of chemical substances such as sulphur, which is harmful for marine life. Lead is known as the main reason for cancer disease. Cancer has become a popular disease in several communes which are called “cancer villages”. Another cause is the awareness of citizens, people always use water for many purposes and then they dump wastewater or garbage directly into rivers, canals and ponds and so on.
